I've tried to preview my final render, however I've noticed that the shadows are casted incorrectly. The problem isn't the positioning. Moving the lights doesn't affect shadows and only makes already illuminated areas brighter if the light source is near them. But even if I put the point light in front of the face, the shadows aren't modified at all. I've tried strenghtening the light and changing its size, however the shadows are still wrong.
Is there any step I've missed? How can I fix this?
